Historically, there is a physical controller (such as a slider) for each channel. On most current control systems, channels are numbers accessed by a numeric keypad. Each channel can control multiple dimmers. A connection device and wiring for powering a lighting fixture from a dimmer. A unique four-digit numeric identity which you can assign to each dimmer. The circuit ID may be the same as the dimmer number, or may be a number used to indicate circuit location, phase, channel number, etc. This feature is useful for system wide control functions. A fade that contains both an up-fade and a down-fade, or any fade where the levels of one cue are replaced by the levels of another cue. The process of recalling a preset from its memory location and putting the result on stage. Preset, Memory, and cue are often used interchangeably. curve dimmer default A device controlling power to a lighting fixture. Two lights on the same dimmer cannot be separately controlled. The original factory settings. DMX512 An ANSI communications protocol standard that describes a method of digital data transmission between controllers, lighting equipment and accessories. Ethernet A high-speed network based protocol used to transmit data from a lighting controller to a dimmer rack using a single Ethernet cable. fade fade time level Outlook A gradual change in stage levels from one set of intensities (“look”) to another. The time it takes for dimmer levels to go from their current levels to the levels in the selected preset, or DMX value. Each preset has its own fade time. A numerical value used to express the “brightness” of the load on a dimmer. Usually shown as %. A digital architectural control system for use with C21/EC21 dimmer racks. patch Historically, the process of physically connecting circuits to dimmers. Now usually refers to electronic assignment of dimmers to channels. phase The three phases of the mains supply to which the dimmers are connected are identified as Line 1, Line 2, Line 3 in 230v markets and as phase A, phase B, and phase C in 120v markets. power module Operations Manual The relationship between a control level and the actual dimmer output. A chassis containing one, two or four dimmer or contactors. This is sometimes referred to as a “dimmer”. However, each C21/EC21 power module can have multiple dimmers or contactors in it, so this manual distinguishes between dimmers (individual power control circuits) and power modules (a collection of one or more power control circuits). Page ii preset Preset fade time profile rack number room A pre-defined setup of intensities for a set of channels, stored in memory for later replay. For Outlook applications, the C21/EC21 series dimmer rack processor module stores 8 programmable presets per room for up to 16 rooms. For SWC applications, the processor module stores 128 programmable presets. Preset 0 (ZERO) is always a blackout. See “Fade Time”. The relationship between a control level and the actual dimmer output. Also known as ‘dimmer law‘ or ‘curve’. A number used to uniquely identify each dimmer rack in a multiple rack system. Rack numbers are set from the front panel of the rack processor module, and are usually set by the installation engineer. An area separately defined for purposes of architectural lighting control (e.g., Outlook control stations). This is usually a room in the traditional sense (an indoor enclosed area) or a portion of a room that can be partitioned off. Each room may be separately and simultaneously controlled by the system. RPH Rack Processor Housing RPM Rack Processor Module SSR (Solid State relay) A power control device used in Strand dimmers that contains two silicon control rectifiers (SCRs), control circuitry, and optical isolation circuitry. SWC (System Wide Control) A method of programming and controlling more than one dimmer rack simultaneously. A hand held controller lets you program and recall 128 presets, and control individual dimmers. 8 and 16 channel pushbutton stations, and an A/V interface let you recall and 8 or 16 of the 128 presets at each station. Please contact Strand Lighting or see the System Wide Control Data Sheet or System Wide Control User’s Manual for details on how SWC works. Technical Assistance C21/EC21 racks and dimmers require a minimum of maintenance and servicing. For operation or technical assistance, please contact Strand Lighting or the local Authorized Service Center serving your area.

Mid-range dimmer racks have provision for up to 36 dimmer modules. Small dimmer racks have provisions for up to 24 dimmer modules. Dimmer modules contain one, two or four dimmers, and dimmer module types can be mixed within a rack in various combinations. Door Hinge Bracket Ventilation Grill Dimmer Modules Door Strike Fan Housing Rack Processor Housing Rack Processor Module Backup Processor Module (Optional) Blank Panel Figure 1 – C21/EC21 Series Dimmer Rack Fully Populated (doors removed) Operations Manual Page 10 Dimmer Modules The power modules are the high power switching section of the C21/EC21 dimming system. The power block in this module is the interface between the high power AC and low power control. It is driven by low level signals (5mA, 3-24V) and switches high level signals (up to 100A, 120/240VAC). High specification filtering, SCR dimming, contactor non-dims, Sinewave dimming, and load status reporting electronics are available as options. Dimmers can be mixed in any combination in a rack. This lets you use the exact dimmer type needed for each circuit. Quad dimming modules are also available in custom racks. Power modules are constructed from aluminum, folded to form three sides of the dimmer and to support the dimmer connector and heatsink. The fourth side of the dimmer is formed by the heatsink. The top and bottom of the dimmer are open for cooling. A sturdy handle is provided below the circuit breakers. An optional mechanical locking bar on the dimmer tray secures the dimmers in the rack. Chokes Connector Circuit Breakers Dimmer Wing With Type & Rating Handle Reporting PCB (optional) SSR or SCR Pack Chassis Figure 2 – Dual Dimmer Module Reporting Dimmer Most C21/EC21 dimmer modules are available in load status reporting versions. Modules Load status reporting versions of dimmers can be mixed in any combination with standard dimmers in C21/EC21 racks. These dimmers report many dimmer status items back to the processor. The information can be accessed through various menu items. The processor can then display a wide range of faults and diagnostic data. Each Reporting dimmer module contains a temperature sensor which will shut it down if it overheats. Anything causing overheating in the rack will cause a gradual shutdown as each Reporting dimmer module overheats. Page 11 C21/EC21 Series Dimmer Rack Fan Module The dimmer racks are cooled by a set of three low noise variable speed fans in a fan module at the bottom of the rack. The cooling system is designed to let the rack continue functioning if any one of the three fans fail. Cooling air is pushed up through the dimmer stack and exhausted through venting at the top of the rack. These fans are for dimmer cooling only, and can be set to fixed or variable speeds. The fixed speed fan setting is for situations where changes in ambient noise are a problem. With this setting, the fans are always ON when the dimmer rack is in operation. The variable speed fan setting minimizes noise and maximizes fan life. With this setting, the fan speed is adjusted so that fans reach full when 24 dimmers are at full, or equivalent (e.g., 48 dimmers at 50%). Increases in fan speed take 1 minute with this setting, while decreases in fan speed take 5 minutes. Fans are turned OFF when no dimmers are in use. Fan Module Grill Filter Figure 3 – Fan Housing Rack Processor Housing Each C21/EC21 dimmer rack contains a rack processor housing (RPH) with all of the control electronics for the rack. This RPH contains the processor module(s) (RPM), control station power supplies, and control interconnection card (CIC) for the rack, and is shipped separately from the rack to minimize the possibility of damage. This chassis can be equipped with one or two processor modules. The second processor module acts as a backup. The configuration data from either processor can be transferred into the other processor. The currently inactive processor always tracks the currently active processor. Power Supplies Backup Processor Module Control Interconnection Card (CIC) Rack Processor Module (RPM) Figure 4 – Rack Processor Housing Operations Manual Page 12 Rack Processor Module Each C21/EC21 rack contains one or two rack processor modules (RPM). Each processor module has a backlit LCD display, a 7 key keypad, and 6 LEDs to report processor module and dimmer status and allow setup and control at the rack. In normal operation, this display normally shows the rack name and the OK message. If there are any rack or dimmer events reported, the display will show error messages. Pressing the < or > keys will takes you into a series of setup menus to view and set up the more frequently used C21/EC21 features. See Section 3, Processor Module Programming for details on accessing these functions. All programmed data is held in battery maintained RAM for up to 6 months without power. Figure 5 – Rack Processor Module Power Supplies Control Interconnection Card (CIC) Each C21/EC21 rack can have up to three power supplies, depending on the accessories provided. These power supplies are mounted on the rack processor housing. The electronics chassis also contains the control interconnection card (CIC). This is where the contractor terminates all control wiring for the rack. All control terminal strips are 2-part plug-in strips so that the electronics chassis can be easily removed from the rack. Processor Configuration Once you have applied power you need to make sure that the system is working correctly and the processor modules are set properly for the installation. This step checks for any problems due to shipping or installation. Startup When the rack is switched ON, a number of self-tests are run. The system displays the rack name. Strand Lighting Rack 1 < or > to select menu Page 13 C21/EC21 Series Dimmer Rack When the self-tests are complete the PROCESSOR OK LED on the front of the processor module will turn ON, and the default text will show on the LCD display.

C21/EC21 Series Dimmer Rack Section 2 - Operational Features Rack Configuration The following configuration items are usually programmed during commissioning, but can also be reprogrammed by the user. Rack name. Panic selection and configuration Maximum output voltage (per dimmer): 20-250 volts (e.g. set to 105V for extended lamp life). Minimum level (per dimmer): 0% - 100% (e.g. set to 10% for aisle lights or large lamp preheat). Room and channel Patching (for applications using Outlook) Each dimmer can be patched to any valid DMX512 address number for the standard input A (DMX A), input B (DMX B) or network. Circuit ID—used by SWC and status reporting software. Record and recall presets (1-8, ON and OFF per room for Outlook control, and 0-128 per rack for System Wide Control). Define Preset Number or “Hold” condition on DMX failure. Define power-up preset per rack for Outlook architectural presets. Set LCD contrast. Error log accessible from the processor module or status reporting software. Individual dimmer reporting enable/disable. Dimmer Configuration Configuration items associated with the dimmer module can be set from the processor module front panel. The output response profile can be set to Linear, Square, S-Curve, FluoElectric (for electronic fluorescent ballasts), Fluo-Magnetic (for magnetic fluorescent ballasts), and Non-Dim. The two fluorescent settings let you set the top end voltage and the bottom end cutoff voltage. The Non-Dim setting lets you set the turn-on threshold for the non-dim. Five additional user programmable profiles are available through the Set Rack Configuration menu or from the optional status reporting software. Dimmer response (per dimmer): fast (30ms), normal (100ms) or slow (300ms). This determines a dimmer’s rate of response to a change in control level. Slow is usually set for large tungsten loads to reduce filament inrush, medium or fast for small loads. Dimmer control assignment (per dimmer) to the “combined” levels of Outlook preset, SWC preset, DMX A, DMX B, Network or to a fixed level (0% - 99% or “Full”). The way in which the various input levels combine is also determined on a per dimmer basis by setting the dimmer DMX mode. A special smoothing algorithm is applied to small level changes to maintain smooth fades with long fade times. Control Inputs The Control Interconnection Card, or CIC, is the printed circuit board on which all contractor control wiring connections are made. It is located on the top of the Rack Processor Housing (RPH) and contains: Operations Manual Page 16 An optional Ethernet switch, which connects to a Strand ShowNet system and is Advanced Network Control (ACN) ready. This switch allows for easy connections between dimmer racks. It also connects to the network receptacle located in the upper left rear of the dimmer rack. Two optically isolated DMX512 control inputs. The first input will accept DMX512. The second DMX512 input is configurable to accept either DMX512, Strand Lighting’s System Wide Control (SWC) dimmer protocol or Strand Lighting’s Outlook architectural protocol. Each DMX input has a patch to allow overlapping or separation of any DMX control level. Six optically isolated contact inputs, for: Pin Function Type Description 1 PANIC ON Momentary Turns Panic On 2 PANIC OFF Momentary Turns Panic Off 3 FIRE ALARM Maintained Turns Panic On, No Override 4 SWC PRESET 1 Momentary Fires SWC Preset 1 5 GO NEXT SWC Momentary Fires “Next” SWC Preset 6 GO SWC OFF Momentary Fires SWC Preset 0 (Blackout) 7 Com/Gnd Com/Gnd 8 Com/Gnd Com/Gnd An Audio Visual Interface port.

UART Configuration: 9600 Baud, 8 data bits, No Parity, 1 stop bit Message Overview: Messages are composed of a short string of printing ASCII characters that request certain actions from the rack processor. Messages are acknowledged by the processor with confirming reply messages or with status update messages. Messages are transmitted as byte streams terminated by designated printing ASCII characters. There is no requirement for line termination. Received characters that do not have a defined function in the protocol are ignored. Operations Manual Page 38 Message Composition: Messages are composed of a single command character, followed by an optional numeric field that may be up to 3 characters long, followed by a single terminating character. Thus, complete messages range from 2 to 5 characters long. Command 1 byte Parameter 0 to 3 bytes Terminator 1 byte For all messages received from the AV controller, the terminating character is the letter ’Z’ in either upper or lower case (0x5A or 0x7A). For all messages transmitted from the C21 Rack Processor, the terminating character is the letter ‘Y’ (0x59). The following messages are defined: Play SWC Preset: Command Code: ‘S’ or ‘s’ (0x53 or 0x73) Parameter: Up to three digits indicating an SWC preset number in the range 0..128. ‘0’ represents the “Off” preset. Action: The rack processor plays back the indicated SWC preset, and responds to the AV controller with the identical message terminated with the ‘Y’ character instead of ‘Z’.

To Factory Menu Page 53 C21/EC21 Series Dimmer Rack Section 4 - Basic Troubleshooting General This section provides basic troubleshooting procedures for C21/EC21 series dimmer racks. It does not provide comprehensive maintenance data, but lets you solve simple problems and helps Strand Lighting with initial data when these procedures are not effective. For best system operation, do a routine check and cleaning once per year unless the operating environment is unusually harsh or dirty. Please consult Strand Lighting Field Service if you are in doubt about the frequency of maintenance required for your system. Service and maintenance operations other than routine checks and cleaning are seldom required. In case of problems, and in order to save time, follow the procedures outlined in this section before calling Strand Lighting. Take note of the results of each step, as you will be asked this information if you call a Strand Lighting service representative. In order to avoid miscommunication, ensure that the person contacting Strand Lighting is the person doing the tests. All servicing except dimmer and mechanical components should be performed by sub-assembly replacement. Control Signal Flow The following diagram illustrates the control signal flow through the dimmer rack. It is included to show how the programmable settings interrelate.
